We just had VDSL installed and the speed appears to be no different from ADSL. The router claims that it's connected to VDSL. Looking at the line attenuation is puzzling as reading through some of these threads we should not even be eligible for VDSL due to the attenuation.

It's an oldish (1940) house, with 3 jackpoints - one upstairs (unused), one with plug -in splitter for VDSL and phone and another with phone/homescan unit (ADSL2+ plug-in filter). Would a second splitter for this last jack be of any benefit, or should I be considering the outside connection and petitioning Slingshot to install a master splitter?

Many thanks for any advice.

Sounds like you need a master filter installed. What provider are you with and furthermore where are you based?

Where is your property on the Chorus coverage maps? Are you within a VDSL2 coverage area, and if so are you near the edge of coverager?


Your stats are very poor, and the first step towards identifying the issue is the installation of a master filter. I'm pretty sure it's still $199 from Chorus. What ISP are you with? Most are now penny pinching now due to the race to the bottom in pricing to won't include by by default any longer.

Thanks for the replies. We're with Slingshot. On the Chorus map we're close to the edge of the VDSL zone, but they 'checked' for suitability before approving the change-over.

The part that's most puzzling is that reading here, an attenuation of almost 30 should've disqualified us from VDSL by a large margin.

It depends how much of that attenuation is caused is caused by 1940s era internal wiring. As @sbiddle has pointed out, a VDSL (or ADSL for that matter) connection won't perform well without isolating all that old wiring - you're asking it to cope with frequencies many times higher than the voice it was originally designed for.


Drop a few of your neighbour's addresses into the Chorus address checker and see if any of them seem to be on VDSL, and what connection speed they are getting - it may give you some idea of how much effect your internal wiring is having.


EDIT: spelling

I don't know how much of the original wiring remains. I know that all the jackpoints are relatively modern, but not the age of the wiring that they splice on to.

I checked the neighbours using the Chorus site as you suggested. Maybe it doesn't work so well for Napier, but the only time it gave me speeds were for existing ADSL connections (14-15 Mbps) otherwise you just get "We are encountering issues completing the request". Also funny is that less than a block down the road (probably around 100m) they're enjoying fibre (sometimes there just seems no rhyme nor reason why Chorus are rolling it out the way they are).

For a master splitter, I'd probably look at doing it myself. Presumably the sooner you split it the better - maybe another fun trip under the house ;-)

Yep, at the ETP if at all possible, where the cable first comes in from the street, otherwise you are not bypassing all the unknown that you need to bypass
